Detect segments with movement.
Detects segments periods further from rotation_velocity_limit, translation_velocity_limit and mean_distance_limit. It returns an annotation with the bad segments.
Raw
Data to compute head position.
array
, shape (N, 10)The position and quaternion parameters from cHPI fitting. Obtained
with mne.chpi
functions.
float
Head rotation velocity limit in radians per second.
float
Head translation velocity limit in radians per second.
float
Head position limit from mean recording in meters.
Identify the device to head transform used to define the
fixed HPI locations for computing moving distances.
If average
the average device to head transform is
computed using compute_average_dev_head_t
.
If info
, raw.info['dev_head_t']
is used.
mne.Annotations
Periods with head motion.
array
Head position over time with respect to the mean head pos.
